claims.

`1 l This invention relates to evaporative air cooling apparatus andmore particularly to water elevating and distributing means forevaporative coolers of the multi-filter type.

The principal object of the invention is to provide improved means fordelivering water in substantially equal volume to each of a plurality ofangularly related lter mats in an evaporative cooler such as describedin U. S. Letters Patents Nos. 2,296,155 and Re. 22,675 wherein side matsconverge rearwardly towards a rear mat disposed transverse to the streamof air caused to pass therethrough by means of a blower situated betweenthe side mats. To avoid the conventional but impractical method ofelevating Water by pump action and distributing the same by means oftroughs located along the upper edges of the filter mats, the presentinvention provides a water elevating unit disposed in the water basin ofthe cooling apparatus which consists of two discs of differentdiameters, one being partially submerged in the water Vof the basin toelevate and transfer water to the other. By virtue of the high speed ofrotation of these discs, water is discharged tangentiallyv off theperimeter of the discs upwardly, the direction of thrust from the largerof the discs being predetermined and controlled by an adjustable baiiieadjacent its periphery while the discharge from the companion disc `iscontrolled by causing water collected off the face of the larger disc toimpinge the confronting face of the said companion disc at apredetermined point thereon.

Another object of the invention is to provide an arcuated watercollecting and distributing plate disposed above the filter mat assemblyagainst which water thrown upwardly by the discs impinges at preselectedpoints. To complete the assembly, the invention further provides watersheds or baffles alongside the side mats into the rear ends of whichwater is discharged from the collecting plate for distribution onto thesaid side mats to saturate the same.

With the foregoing objects as paramount, the invention has furtherreference to certain features of accomplishment which will becomeapparent as the description proceeds, taken in connection with theaccompanying drawing wherein: Y

Figure 2 is a detail perspective View of the arcuated collecting anddistributing plate per se.

` Figure 3 is a fragmentary perspective view of istv one of the sidemats, showing a Water shed and the relationship therewith of thecollectingr and distributing plate, the latter being fragmentarily shownin dotted lines.

Figure 4 is a perspective view of the Water elevating unit.

Figure 5 is a side elevational view thereof on enlarged scale, and

Figure 6 is a rear elevational view of the water elevating unit.

Continuing with a more detailed description `of i the drawings,reference is primarily made to Figures 1 to 3 wherein numeral I0 denotesa cabinet of conventional design and also conventional are the airiilter mats II and I2. The mat II is disposed at the rear and the sidemats I2 are disposed at relative angles and converge rearwardly, thusdefining between their outer surfaces and the side walls of the cabinetsubstantially triangular spaces serving as moisture collecting chambers.The mat assembly is mounted removably on skids I3.

As stated. it is the intent of the invention to provide for equaldistribution of water on the mats II and I2 from a single point withoutthe aid of a pump and distributing troughs usually situated above themats or along their upper edges. Due to the necessity in many cases formounting the cooling unit outdoors, it is impossible to obviatecollection of foreign matter in the water of the basin I4 and thisforeign matter not only causes frequent fouling of the pump but ifelevated with water delivered by the pump, such foreign matter collectson the mats and in the case of animal and vegetable matter decayingthereof gives rise to unpleasant odors difiicult to remove.

As will become apparent presently, the invention provides a single unitfor elevating and distributing water to all of the mats simultaneouslyand the very minimum of foreign matter reaches the mats by virtue of thefact that gravity will cause the heavier of the particles of solidmatter to precipitate out of the streams of water as they are projectedupwardly to be transported in part to the side mats and caused to enterthe rear mat under influence of the blower.

Accordingly, the water elevating unit consists of a base I5, the rearportion of which is formed with Va narrow cavity having a curved bottoma (Fig. 5). A portion of the base extends forwardly and is disposedrearwardly of a disc I6 which may, for identication purposes, bereferred toY hereinafter as the major disc while a smaller disc I'I,mounted on the samev axis I8wil1 be re1- ferred to as the minor disc. Itis to be noted in Figure that the perimeter of the major disc conformsnearly to the contour of the bottom a of the cavity in the base intowhich part of the major disc extends. The shaft I8 of the two discs isjournaled in bearings I9 mounted or formed on the top of the baseelement I5.

The base I5 is provided with supporting arms 20 which are bolted orotherwise secured to the skid I3 supporting the rear mat I I and bywhich the said base is mounted.

Mounted on one side of the base I5 is a stripping tube 2| whose endnearest the major disc I6 is of greater width than the discharge ornozzle end b which is in juxtaposed relation to the confronting face ofthe minor disc I'I and spaced inwardly from the perimeter thereof.Moreover, it is pointed out that the tube 2| is disposed at an angle tothe plane of the face of disc I'I for the purpose to become apparentpresently.

The stripping tube 2| has a lip 2v2 overreaching the edge ofthe cavityin the base in which the major discY I6 operates and this lip is in nearcontiguity with the face of said' discr I6 and parallel therewith.

The base I5 is but partially submerged in the water of the basin. I4 toa depth insulicient to permit the minor disc I1 to enter the' water. Thewater level at its peak is suggested byV the dotted line crossing Figure5 and is show-n' to be below the minor disc I1 but the disc I5 is shownasbeing partially submerged.

A motor 23 (Fig- 1V) adequately sealed against moisture is disposed'inwardly of the rear mat Il and drives shaft I8 at a high rate ofspeed', causing the discs I6 and ILI to revolve at the same speed. Wateris elevated by the disc I6 by surface tension and is stripped off by thelip 2.2 of tube 2i and caused thereby to be projected through the tube2I onto theface of the rapidly revolving disc I'i. The water isdischarged tangentially olf the disc II, taking the path substantiallyas shown by arrows in Figure l or towards the upper left hand cor-nerofthe cabinet 91 and in impinging the downwardly curved portion c of acollecting and distributing plate 24, the water follows the curve ofthe-plate and fallsupon the' extendedV end25 (Fig. 3) of a shed orbaffle 2B.

As shown in Figure 3, the sheds 25 which are identical in constructionand-position on each side of the cabinet, occupy the triangular moisturecollecting chambers between theside pads l2 and side walls of thecabinet. The sheds are-slightly inclinedtowards the rear of the cabinetas welll as laterally towards the side mats I2 and their inner ordischarge edges lie in recesses il' (Fig. '3i in the outer surfaces ofthe mats. Hence, the water delivered onto the ends of these sheds by thecollectingplateZwillflow at oncetowards the forward end ofthe shedandoithedischarge edge thereof' throughout its length to enter theadjacent mat and maintain saturationthereof.

Simultaneous with the foregoing function a separate dischargeofwate-rvis made off theperirmeter of the major ,disc Iwhichtales-thecourseshown by the arrows to the right4 inFigu-re l, i. e., upwardlytowards and against the-'downwardly curved endvd ofthe collectingplatel, to be discharged thereby onto theeXtended end 2550i the oppositeshed Y 2" and similarl.v distributed along the outer surface of thecompanion sidey padnear its top, shown. Y

It is to be particularly observedthat the curva'- ture of thecolllecti-ng-platet do'esn'otrepresent a true centered arev but insteadis distortedv to dispose the portion e having the deepest curve nearerthe right of the rear mat. The object in so doing is to insure thatwater in adequate quantities will be transferred by surface tension andgravity along the gradually sloping undersurface of the plate 2d' to thedownwardly curved end c and onto the water shed 26. It is less difficultto adequately supply the shed to the right of the cabinet, hence thearrangement described. Obviously, there will be a radial discharge fromboth discs I5 and I'l throughout the effective radius but the greaterdischarge will be as described and shown, i. e., towards the uppercorners of the cabinet.

While not shown, it is understood that a conventional blower is disposedbetween the side i mats I2 and forwardly of the rear mat il to cause airto be drawn through the mats and to discharge the same at the front ofthe cabinet into a room or enclosure. Suction of the blower willconstrain water thrown upwardly by the discs to enter the rear mat I I',saturating the same and also into the moisture collecting chambers ateach side of the cabinet where the water will, in part, be influenced toenter the side mats supplementing'that precipitated by the sheds 26, asdescribed.`

In order to control the direction of discharge as wellV as the quantityof water thrown by disc I6, a baiiie 28, consisting of a small, curvedplate, so identified', is mounted adjacent the point of the greatestdischarge of disc I6 and is supported adjustably by an armv 29, attachedby means of screw 3Q tothe base mounting I5. It is apparent that thisbaille 28 may be moved towards and away' from the periphery of the discI5 to respectively decrease and increase the quantity of water dis-`charged 'thereby' as well as to change slightly' the directiono'fdischarge. It isfuriher apparent that the confined. space in. whichthe disc it' is constrained to'operate',.combined with the curvedbottoma ofthe cavity, limits the width of the discharge.. the said'.curved bottom' a being especially effective to establish ahead of waterwhich remains Vconstant so long as the level in the basin is constant. v
